2009.
Gram-positive cocci, 0.6–1.1 μm, occuring singly or in pairs, tetrads or clumps. Non-
motile. Non-spore-forming.
Colonies are white, circular, convex, smooth, non-translucent with entire margins, 1–2
mm in diameter after incubation at 25 ºC for 3-5 days on Marine Agar supplemented
with 10.0% NaCl. No diffusible pigments are produced. Moderately halophilic: grows
in optimum 10.0% NaCl (range1.0-30.0% NaCl). Optimum pH is 8.5 (range 6.0-10.0).
Optimum growth temperature is 25 ºC (range 5-40 ºC). Strictly aerobic.
Isolated from a brine sample collected from the Yipinglang salt mine in Yunnan, southwest China.
Resistant to gentamicin (10 μg), kanamycin (30 μg), lincomycin (2 μg), polymyxin B (30 μg) and streptomycin (10 μg). Susceptible to
ampicillin (30 μg), chloramphenicol (30 μg), nalidixic acid (20 μg), novobiocin (30 μg), rifampicin (5 μg) and tetracycline (30 μg).
Undetermined.
